According to advance estimates, it would take more than 50 minutes for Robin to lead the Tiger Battalion into the stone tree before they could reach the city of Pulì, which is located at an altitude of meters. For a combat operation for the purpose of surprise attack, the diving time of more than 50 minutes can be said to be very long, but what Robin did not expect was that the strange ecological environment of the stone tree made people feel the passage of time at all, and the time of more than 50 minutes seemed to pass in a flash, and in the blink of an eye, they had dived to a height of more than 6,000 meters and arrived at the top of the Pulì Mamu tree.

During this long float that lasted for more than 50 minutes, they witnessed countless strange things.

Some of these creatures are very similar to marine life on Earth, while others are new species that have never been heard of before.

As a biologist, Lì Ona naturally did not miss such a rare opportunity, and she collected all the biological samples at her fingertips without affecting the speed of the troops' movements. As a result, she found that the layout of the creatures in the stone tree is actually very similar to the oceans on the earth, and the same different depths are used as dividing lines, giving birth to various creatures.

Just like the deep-sea creatures and shallow sea creatures in the earth's oceans, the species in the stone trees also have great differences in size and structure depending on the depth at which they are located. However, because the density of the body fluid of the stone tree is far less than that of water, and the water pressure formed in the body of the stone tree is not so huge, the difference is not as obvious as that of marine life on the earth, but some invertebrate mollusks like octopuses have developed to a high level, and have begun to show a relatively primitive social model, with some of the most basic characteristics of intelligent organisms.

"If it is given enough time to evolve, I am afraid that in a million years, it will become a new intelligent species that threatens humanity." Let go of the desperately struggling "little octopus" in her hand, Lì Ona said to Robin in a mocking tone.

Hearing Lì Ona's words, Robin turned his head to look at the "1 little octopus" that was swimming away quickly, and smiled: "Then should I get rid of them now?" ”

"Didn't you say you're not a visionary?" "Haha...... yes, a million years from now! ~It's hard to say whether human beings will still exist at that time. Robin withdrew his gaze from the "1 little octopus," "Ansel, report where we are at the moment." At 47°34 N, 7 east longitude, Si Er casually looked it up and continued: "From the coordinates, we should be located on the southwest side of District C of Pulì Ma, where the residential area is located."

"Residential area? The location was good and perfect for us to dive into. Robin nodded and ordered, "Barrett, Taber, Barrett, Tabber, you go up first, pay attention to concealment!" ～”

"Yes! ～”

Upon receiving Robin's order, the Taber brothers immediately ascended along the inner shelter of the stone tree, plunging headlong into a dense algae colony with a thickness of 100 meters.

Using the cover of green algae, the Taber brothers quietly approached the water, observed the surrounding environment with a periscope that could be adjusted from the angle under the water, confirmed that it was safe, and jumped up from under the water to land on the nearest ground.

The city of Púlì Mar in the sky covers an area of 5,488 square kilometers and was home to about 200,000 people before the mutant rebellion. Due to its large and sparsely populated area, the city's buildings do not cover the entire tops of the Pulì Mamu tree. If you look down from above1

The urban layout of the city is like a loose spider web, with countless branch roads intersecting on the verdant lake, and buildings with strange styles sitting in the water, separated by large areas of water, looking very much like the water city of Venice in the old days.

Today, the Taba brothers are located on the southwest side of Block C of Pulìma, nearly a thousand kilometers from the edge of the heavily defended city, and about the same distance from the center of the city, so this area happens to be the most poorly defended. Moreover, after the invasion of the mutant rebels, the residents of the city and the replicant mechanics who work here have been concentrated by the rebels in the industrial area located at the base of the Pulì Mamu tree, so the entire residential area of Area C can be said to be empty at present, and no one will find that a force has quietly landed here.

After the Taba brothers quickly occupied the surrounding commanding heights and implemented a guard, the main force of the Tiger Battalion immediately landed as fast as possible under the leadership of Robin. Looking from afar, I saw figures covered in green algae rushing out of the water, rushing towards a occupied house without stopping.

"Give you three minutes to equip! ～”

After taking off their diving suits and changing into heavy infantry armor in the shortest possible time, the first batch of equipped soldiers immediately followed Robin, who was equipped with "Shura," type armor, to leave the dwelling and spread out on the interconnected city arteries, advancing in echelons towards the center of the city.

Due to the heavy losses of the anti-aircraft fire system in the city due to air raids, the mutant rebels occupying the city have focused most of their efforts on repairing the anti-aircraft fire system, so the guards in the city are very lax. Robin, who was the vanguard, did not even notice the existence of any enemy after advancing nearly a hundred kilometers at a rapid pace.

"It's so quiet, it's quiet, it's like a dead city." Anse El was close behind Robin, unsettling at the oppressive silence at the moment.

"How far is it from the main control tower?" Robin asked, frowning.

"There are about seven hundred kilometers or so, do you need to assemble infantry vehicles to break through?"

"Why not, since there are no patrolling guards in this city, then we don't need to move forward as slowly as we do now." Robin made a static gesture and ordered, "Xia Zuo, you lead the second echelon to continue to advance on foot. The first echelon immediately hid itself on the spot and carried out the assembly of infantry vehicles! ～”

Due to the material assistance received from the Republic, the entire Tiger Battalion is equipped with the most advanced "Thunderbolt, I Individual Maglev Locomotive" in the Republic at present. "The Thunderbolt, Type I, has a simple, lightweight, and easy-to-carry structure, which is very much in line with Robin's special operations needs. Therefore, before the implementation of this tactic, each soldier of the Tiger Battalion stored his own heavy infantry armor and individual weapons in his equipment box, as well as "Thunderbolt, Type I assembly parts, which can be assembled on the spot at any time according to the needs of the operation."

With the cooperation of the various groups, the first echelon of 50 people led by Robin quickly completed the assembly of the body of the "Thunderbolt, Type I individual maglev locomotive, which made the unit suddenly evolve into a highly mobile mechanized force, and quickly marched towards the main control tower that controlled the anti-aircraft fire system in Pulì City.

Robin's decision to equip the troops with "Thunderbolt, the I-type individual maglev locomotive is actually a very bold adventure, because such a large-scale breakthrough is difficult to hide from the detection radar in the city, as long as the detection radar detects that the body number used by this mobile force does not belong to the city's equipment sequence according to the thermal response, then the defenders can find this enemy army lurking in the city at the first time. But Robin decided to take the risk because he knew that each nobleman had his own artificial intelligence, which was only responsible to the nobleman himself, and oversaw all the properties under the nobleman's name. Therefore, as the domain of Baron Di Williams, the main control tower of Pìma City is also under the supervision of artificial intelligence. It was the invading rebels who cut off the data connection between the city and the artificial intelligence that enabled the computer system to be activated, but in this way, the main control tower was bound to lose most of its energy and could no longer respond in time as it normally would.

Robin takes this into account ... [This chapter is not finished, please click on the next page to continue reading!] ］
